Packer was sentenced to two years in prison in 2014 after pleading guilty to assault occasioning actual bodily harm.
The conviction saw his lucrative four-year contract with the Newcastle Knights terminated before he could play a game for the club, having played with the NZ Warriors until the end of 2013. He was released in 2015 after spending 12 months behind bars.
He was given another chance in the NRL in 2016, signing with the St. George Illawarra Dragons where he spent two seasons before signing on with Wests Tigers for 2018.
